I enjoy designing / manufacturing game components and upgrades. Got a project? PM!

Looks like a Latrunculorum variant, sure, but no ancient rules have survived(?). No doubt there were plenty of variations over time and place to boot. For instance, that board is 16x? ... that's pretty unusual in itself based on my readings.

Also, the set of bits seems incomplete

Have they checked the back of the board? Inside the box lid? I hear sometimes rules are inscribed there.
